A member of a White supremacist gang was arrested Saturday after he hit a person in the head with a beer bottle while yelling racial slurs, Mesa police said.

Joseph Burgoyne, 28, is accused of yelling racial slurs at a Black patron at Denim & Diamonds, a country bar in Mesa, before assaulting the person with a beer bottle, according to Det. Esteban Flores, a spokesman for the Mesa Police Department.

Witnesses said Burgoyne continued to yell racial slurs until he left the property, records show.

The extent of the patron's injuries was not available.

Flores said the incident is being investigated as a hate crime.

Burgoyne continued to be held Monday in a Maricopa County jail on suspicion of aggravated assault and gang crimes, police records show.
